Essendon livewire Orazio Fantasia's season could be over after scans revealed the extent of a hamstring strain which he suffered in the first quarter of his sides win over Carlton on Saturday.

The club's High Performance Manager Justin Crow told BomberTV that the strain will keep the forward out for the next five to six weeks despite the muscle not being torn.

"At the time it looked like quite a serious hamstring," Crow said.

โ€œThe scan results show itโ€™s a grade two plus, which means heโ€™s going to miss five to six weeks.

โ€œHeโ€™ll need everything to go right and weโ€™ll start to progress him up as heโ€™s able over the coming week.โ€

In more positive news for the clubs forward stocks, spearhead Joe Daniher was cleared of any structural damage after he hyper-extended his knee during the match.

โ€œHis knee hyper-extended and sometimes when that happens you can get some really bad injuries,โ€ Crow said.

โ€œFortunately for Joe and us he got away with it.

โ€œHe was a little bit sore in his knee but he was able to play out the game and heโ€™s looking pretty good this week and heโ€™ll train tomorrow.โ€

James Kelly and rookie Andrew McGrath will be available for selection against Adelaide after being rested against the Blues last week.

โ€œBoth of those guys are jumping out of their skin, they really sharpened up over the weekend, theyโ€™re looking forward to training tomorrow and weโ€™ll expect them to give us a real burst on the weekend,โ€ Crow said.
